The event, which takes place on June 12 and airs on Spike TV, features a main-event rematch of Spencer Fisher (19-3 MMA, 4-2 UFC) vs. Sam Stout (11-2-1 MMA, 1-1 UFC). In one of the year’s best fights, Fisher (a late replacement for Kenny Florian) dropped a close split-decision to Stout at UFC 58 in March 2006.

The Tibau vs. Cox bout could appear on the same main card and make the televised portion of the event.

Tibau has two previous fights in the UFC: a TKO loss to Nick Diaz at UFC 65, and a unanimous-decision win over Jason Dent at UFC 68 in March. The 23-year-old Brazilian and American Top Team fighter trains out of Coconut Creek, Fla., and should be a solid draw for the local crowd.

He’ll face Cox, a UFC newcomer and King of the Cage veteran who began his career 5-0. However, he’s just 3-3 in his past six fights, which included a 2005 KOTC loss to current UFC welterweight Thiago Alves. The police officer trains out of Cleveland with current UFC fighter Forrest Petz.

What makes Cox an interesting choice for this fight is his age. At nearly 40 years old, he’ll be one of the oldest fighters ever to debut with the UFC. He’s recently spoken out about what he perceives to be age discrimination against fighters who are 35 and older, saying they undergo more rigorous medical exams than their younger counterparts — oftentimes without cause.
